The cylindrical carriages rotate so the floor is always level, adjusting to changes in gradient and allowing passengers to remain vertical, even as the tram climbs towards the Alpine plateau at inclines of 110%.

Each carriage can carry up to 34 people, and will travel at speeds of 10m a second. The journey takes just four minutes.

During that four minutes you'll be treated to amazing views as your climb.

Previously, the world record was held by the Gelmerbahn at Bern (with a gradient of 106%), while it’s nearest rival in England is the East Hill Cliff Railway, with a measly gradient of 78%.

“After 14 years of planning and building, everyone is very proud of this train,” said railway spokesperson Ivan Steiner.
